Post-transplant lymphoproliferative disorders (PTLD) are complications that arise from post-transplantation immunosuppressive therapy. Although Epstein-Barr virus (EBV) viremia is often seen in PTLD, it is not a definitive feature for diagnosis. We report a rare case of recurrent PTLD in a 26-year-old heart transplant recipient on high-dose tacrolimus who presented with emesis, fatigue, and bloody diarrhea. Although substantial EBV viremia was seen in the first PTLD episode, the current episode was a gastrointestinal manifestation with barely detectable circulating EBV. The patient's history of gastrointestinal disease delayed definitive diagnosis, which was later established through endoscopy and biopsy sample analysis.

Central nervous system (CNS) involvement by lymphoproliferative disorders is rare and associated with a poor prognosis. CNS involvement can be exclusive, primary or appear in a secondary manner as part of a systemic process. The spectrum of involvement that we encounter is varied and neuroimaging plays a key role in diagnosis.

The oncogenic Epstein-Barr virus (EBV) can drive tumorigenesis with disrupted host immunity, causing malignancies including post-transplant lymphoproliferative disorders (PTLDs). PTLD can also arise in the absence of EBV, but the biological differences underlying EBV(+) and EBV(-) B cell PTLD and the associated host-EBV-tumor interactions remain poorly understood. Here, we reveal the core differences between EBV(+) and EBV(-) PTLD, characterized by increased expression of genes related to immune processes or DNA interactions, respectively, and the augmented ability of EBV(+) PTLD B cells to modulate the tumor microenvironment through elaboration of monocyte-attracting cytokines/chemokines.

Post-transplant lymphoproliferative disorders (PTLD) are a heterogeneous category of disease entities occurring in the context of iatrogenic immune suppression. Epstein-Barr virus (EBV)-driven B-cell lymphoproliferation represents the prototype of quintessential PTLD, which includes a range of histologies named nondestructive, polymorphic, and monomorphic EBV+ diffuse large B-cell lymphoma (DLBCL) PTLD. While EBV is associated with the majority of PTLD cases, other drivers of lymphoid neoplasia and lymphoma transformation can occur-with or without EBV as a codriver-thus underlining its vast heterogeneity.

Post-transplant lymphoproliferative disease (PTLD) is a rare but life-threatening disease that occurs after organ transplantation. Histopathology is the gold standard for the diagnosis of PTLD. Because of its rarity and atypical symptoms, many patients are misdiagnosed with liver abscess, liver cancer, or missed diagnosis long before pathological diagnosis is obtained, thus delaying treatment.
